The neutrinoless double β-decay of nuclei is reviewed. We discuss neutrino mixing and 3 × 3 PMNS neutrino mixing matrix. Basic theory of neutrinoless double β-decay is presented in some details. Results of different calculations of nuclear matrix element are discussed. Experimental situation is considered. The Appendix is dedicated to E. Majorana (brief biography and his paper in which the theory of Majorana particles is given)

Neutrinoless double-beta decay. A brief review
In this brief review we discuss the generation of Majorana neutrino masses through the seesaw mechanism, the theory of neutrinoless double-beta decay, the implications of neutrino oscillation dataExpand
Neutrinoless Double Beta Decay and Heavy Sterile Neutrinos
The experimental rate of neutrinoless double beta decay can be saturated by the exchange of virtual sterile neutrinos, that mix with the ordinary neutrinos and are heavier than 200 MeV.Expand
Near Maximal Atmospheric Mixing in Neutrino Mass Matrices with Two Vanishing Minors
Abstract In the flavor basis there are seven cases of two vanishing minors in the neutrino mass matrix which can accommodate the present neutrino oscillation data including the recent T2K data. It isExpand
Neutrinoless double-beta decay and seesaw mechanism
From the standard seesaw mechanism of neutrino-mass generation, which is based on the assumption that the lepton number is violated at a large (∼1015 GeV) scale, it follows that the neutrinolessExpand

The most important open problems of the today's neutrino physics are the absolute values of the neutrino masses, the determination of the Dirac or the Majorana character and better measurements ofExpand
Heavy Neutrinos and Lepton Number Violation in lp Colliders
We discuss the prospects of studying lepton number violating processes in order to identify Majorana neutrinos from low scale seesaw mechanisms at lepton-proton colliders. In particular, we considerExpand
Broken S-3 symmetry in the neutrino mass matrix and non-zero theta(13)
We study the effects of breaking S-3 symmetry in the neutrino mass matrix for the masses and mixing matrix of neutrinos. At zeroth order the model gives degenerate neutrino masses and accommodatesExpand
Combining and comparing neutrinoless double beta decay experiments using different nuclei
A bstractWe perform a global fit of the most relevant neutrinoless double beta decay experiments within the standard model with massive Majorana neutrinos. Using Bayesian inference makes it possibleExpand
Lepton number violation in tau lepton decays
Recent studies of novel four-body lepton number violating decays of $\tau$ leptons and neutral $B$ mesons are summarized and updated. These decays are assumed to be enhanced by the exchange ofExpand


Double beta decay
We review the recent developments in the field of nuclear double beta decay, which is presently an important topic in both nuclear and particle physics. The mechanism of lepton number violationExpand
Double Beta Decay, Majorana Neutrinos, and Neutrino Mass
The theoretical and experimental issues relevant to neutrinoless double beta decay are reviewed. The impact that a direct observation of this exotic process would have on elementary particle physics,Expand
CP Properties of Majorana Neutrinos and Double beta Decay
Abstract It is pointed out that in theories with CP invariance and two (or more) massive Majorana neutrinos the relative sign of their CP eigenvalues is significant. For opposite values of the CPExpand
Calculation of 2ν and 0ν Double-Beta Decay Rates
